I'm just going to insert this link to a forum about passing down hidden abilities in PBB.

In conclusion, quoting Frould "HIDDEN ABILITY CANT BE PASS DOWN!!! 'WHY? 'Blame Lando64000 he just don't want us to have an ez HA,"

To make things even easier to understand. Even if one of the parents has a hidden ability, the rate of the egg having a hidden ability would still be 1/512 (1/256 with gamepass). Thus, it would make no difference whether the parents have a hidden ability or not because the odds of hatching an HA pokemon would be unchanged.
